Dr. Peter Teng is a general cardiologist who has cared for patients with all types of heart conditions and issues for more than 15 years. He has a special interest in using CT imaging in coronary care and was among the first cardiologists in San Francisco to adopt coronary CT angiography for his patients, having helped establish a CT imaging program in 2007. In addition to noninvasive imaging of arteries of the heart, Teng performs routine cardiac catheterization (a diagnostic or therapeutic procedure in which a long, thin tube called a catheter is inserted into an accessible blood vessel – such as one in the groin or wrist – and threaded up to the heart). He also specializes in echocardiography (using ultrasound to capture images inside the heart and the valves attached to it), cardiac nuclear perfusion studies (a type of stress test using imaging that shows the blood throughout the heart before and after exercise) and pacemaker implantation and maintenance.

In research, Teng studies the ways atherosclerosis (hardening of the arteries) begins and worsens, as well as methods used to better understand the signal pathways within blood vessel cell walls. He also studies the factors involved in the creation of clots in the heart that may lead to stroke.

Teng earned his medical degree at Rutgers New Jersey Medical School. At New York – Presbyterian Hospital, he completed a residency in internal medicine, followed by a research fellowship focused on atherosclerosis, then a fellowship in cardiology at Stanford Health Care. He is a fellow of the American College of Cardiology.

A New York native, Teng comes from a family of educators, which has fueled his natural inclination to educate his patients and help train and mentor residents and students. He was recognized in 2015 as a Castle Connelly Top Doctor in cardiovascular care in the Bay Area and has remained on the list every year since. In addition, he is committed to contributing meaningfully to the transformation of health care by exploring ways that applicable technologies can help simplify and improve patient care while also addressing the variety of challenges caregivers face.

Outside of work, Teng enjoys swimming for wellness, playing piano with his sons and reading the New Yorker, when time allows.

    I would recommend Dr. Teng with the caveat that UC is hard to deal with. The referral took awhile to process. I was discouraged about making an appt. The staff wanted to assign me a cardiologist if I didn't provide a referral. This was not an emergency so no harm was done.
    Aug 30, 2022
    Dr. Teng is very attentive and seems to be so knowledgeable about heart issues. He really listens and answers my questions so that I understand what is happening.

    Dr iwei teng Didn't even let me finish talking and explaining my concerns prior prescribing me a medication. He didn't know why I was there and kept referring to wrong information when discussing my information. I will not be returning to this dr he was terrible.

    Just the way it SHOULD be

    The care provider discussed in detail about my condition and best possible treatment. Appreciate his time and effort.
    Jan 14, 2022
    Warm and friendly towards patients and clear in giving advice and treatment plan.
    Dec 29, 2021
    I have seen a lot of doctors over the last few months for a new condition. Many of them have been attentive and smart and kind. But I felt Dr. Teng was unique in his willingness to think broadly about the issue to consider how factors not related to his specialty might be playing a role and to think creatively about causes. He was very empathetic and also thorough -- I appreciated him ordering additional testing to rule out certain things.
    Dec 13, 2021
    Entirely a very Positive meeting.
    Nov 22, 2021
    Good: He seemed to be a good provider that I could trust.Bad: not really bad but I wish it was an in person meeting. There were times that I can't hear the provider. Like it's on mute.
    Oct 21, 2021
    The big issue was Dr. Teng couldn't immediately see my blood test results until near the end of the visit. So we wasted some time having me show him my results. I finally found it. I chalk this up to new systems.
    Sep 22, 2021
    Dr. Teng was very personable and an attentive listener as I described the background to my concerns leading up to this visit. He asked both standard and insightful follow up questions. He afforded me the time to ask questions and discussed matters through with me at no time making me feel rushed or reluctant to continue. Concerns about the health of one's heart are frightening enough so Dr Teng's patience and attentiveness during our consult were calming and reassuring.
    Sep 22, 2021
    I am delighted to meet Dr. Peter Teng. He's so personable and a great listener. I chose him because my primary care doc suggested him and his profile fit my personal needs. I hope to have him as my doctor for a long time.
    Aug 02, 2021

    Dr Teng is a great doctor. He takes time to listens to patient and share lab reports and explain results. He does not rush off like most cardio doctor.
